1/4 Riyal - Abd al-Azīz Hejaz and Nejd and Dependencies

Abd al-Aziz ibn Saud unified the Hejaz under his control in 1925 after a two-year military campaign that ended Hashimite rule, and the "Hejaz and Nejd and Dependencies" coinage that followed was among the first steps toward a unified monetary system for what would formally become Saudi Arabia in 1932. These transitional issues were struck at the Mecca mint, one of the few instances in the twentieth century of a functioning state mint operating within the holy city.

The .830 fineness matches the old Maria Theresa Thaler standard familiar to Arabian Peninsula traders, a deliberate choice to ease commercial acceptance.
